I will talk about two topics in this discussion. The first being about important concepts that I discovered in the electrical power systems talk. This will include a discussion on the current battery of choice for the ISS and on protection systems for the SAWs (Solar Array Wings) against MMOD (Micrometeoroids and Orbital Debris). The second discussion topic will include how this information can possibly aid to the thought of designing a rover. The four key traits in this discussion are reliability, sustainability, life duration, and redundancy. You will find that the layout of this discussion is in order, as found below.
Topic I
I have to say that most of the topics covered I had previously discovered in the past, however I found it very interesting that the ISS uses Nickel-Hydrogen batteries. I never thought about the type of batteries the ISS used until now. The choice of this battery makes since, especially for when it was designed and constructed. Compared to other rechargeable batteries the NiH2 battery has a decently long life cycle of about 15 years or greater, and has a good specific energy. Furthermore the NiH2 has a great tolerance of overcharging and accidental reverse polarity. This are very key topics that must be considered when choosing a sustainable reusable battery. The only thing that concerns me with this choice is the harder more complex structure of the battery and a decrease (possibility) in safety. These batteries contain pressurized hydrogen gas up to 87 BAR. This means the housing must be rated for pressure, thus they are a bit more costly and more resource rich. Now as far of safety think of the Hindenburg accident, that was also hydrogen. Hydrogen gas can be very dangerous and it especially does not he...

...reaction, thus giving off heat. To control the heat I would just use a potentiometer, allowing me to control the overall temperature of the electrical bay.
The ISS is an amazing station with an even more amazing electrical system onboard. Understanding its vast electrical layout really aids in the design of other electrical systems designed for space. In the future electrical systems will be redefined and vastly superior thus creating a greater potential for space exploration. In designing the electrical system for a Mars bound robot, there are many more considerations that must be made to increase the overall probability of success. However those were the four key traits that stuck out to me the most. I want to thank NASA for that webinar, it was very good and well thought out. I hope you enjoy my discussion and I look forward to hearing from everybody’s comments.

The beaker of water was placed on a hot plate and the water’s temperature was brought to a gentle boil.
Specific Purpose: My specific purpose is to inform my audience about India’s first Mars Orbiter.

Even though we have confirmed the possibility of colonizing Mars, there are certain limitations posed by our current technology and by the space environment that could make traveling to Mars lengthy, expensive, and dangerous.
This is expressed as Δ +ve (delta positive). If the total energy put in is less than the energy created, then the substance warms up (it is exothermic). This is expressed as Δ -ve (delta negative). I will investigate eight different alcohols using an alcohol or spirit burner, to measure the energy change during burning by measuring the change in temperature of some water held in a container.
The Mars Rover is an AMV (Automated Motor Vehicle). NASA uses landers and rovers. Rovers have several advantages over the landers. They can examine more territory, they have a lot more interesting features, and they can be in any kind of weather.
Land Rover paved the way for today’s luxury utility vehicles and it is the Range Rover line that supplies the benchmark by which all other players are judged. The full-size Range Rover is the flagship model, available in standard (short) and extended (long) wheelbase trims. If you want the ultimate blend of British design, craftsmanship, and off-road capabilities, look no further than the 2017 Range Rover.
Thesis: I'd like to start by giving attention to unmanned spaceflight, looking into a few notable discoveries made by these technologies. I will then bring together how these findings have fueled the desire for a continual presence of mankind in space, which can seen through the inception of the International Space Station.
This report will go through the main objectives, all the missions, their findings and any future plans of the Mars exploration program.
In general batteries are into two categories. Primary batteries are non-rechargeable and are commonly found in consumer electronic products. Common primary batteries include zinc-carbon, zinc-alkaline-MnO2, zinc-air, and lithium batteries. Secondary batteries are distinguished by their ability to recharge. Examples include lead-acid, Nickel-Cadmium (NiCad), Nickel-Metal Hydride (NiMH), and Lithium-ion (Li-ion) batteries. For vehicular applications, secondary batteries are the preferred for power source or load-leveling devices. Other possible options include fuel cells and ultra-capacitors.
A well known project failure, although old, is a good teaching point on a highly visible project that was not managed well from the top down. The Mars Climate Orbiter mission was conducted under NASA’s “Faster, Better, Cheaper” philosophy. Although this was thought to enhance innovation, productivity and cost-effectiveness of the program, the program manager should have advised caution when discussing the scope, time, and cost goals with the stakeholders. The 2000 report by the board stated “The success of “Faster, Better, Cheaper” is tempered by the fact that some projects and programs have put too much emphasis on cost and schedule reduction. At the same time, they have failed to instill sufficient rigor in risk management throughout the mission lifecycle. These actions have increased risk to an unacceptable level on these projects.” (Mishap Investigation Board, 2000).
The temperature is then reduced slightly and maintained at the simmering point where the liquid is just moving.
